Are Shock Troops wasted if you call in only a single squad? You don't have to spam an ability to make it worthwhile.
Shock Troopers as AI commander ability is very powerful and got good timing,although IR.stg44 powerful unlock at 3cp,but you need SWHQ first,and Ober already have MG34 upgrade
As UKF and USF,they have weapon rack for all infantry already,if assault section give all squad Thompson or IRstg44 /flamethrower upgrade replace by callin a squad already upgrade it,I have no problem with it
